Hydroxypropyl methyl selulose muri sima na gypsumu ishingiye kuri plaster

HPMC Hydroxypropyl methyl selulosemuri sima ya sima na gypsum slurry, cyane cyane bigira uruhare mukubungabunga amazi no kubyimba, birashobora kunoza neza gufatira hamwe no kurwanya sag.

Ubushyuhe bwo mu kirere, ubushyuhe n’umuvuduko w’umuyaga birashobora kugira ingaruka ku gipimo cy’amazi y’amazi muri sima ya sima hamwe n’ibicuruzwa bishingiye kuri gypsumu. Mu bihe bitandukanye rero, wongeyeho hydroxypropyl methyl selulose ingano yingaruka zo gufata amazi yibicuruzwa bifite itandukaniro. Mu iyubakwa rya beto, ingaruka zo gufata amazi ya slurry zirashobora guhinduka mukwongera cyangwa kugabanya umubare wa HPMC. Kugumana amazi ya methyl selulose ether ku bushyuhe bwo hejuru ni ikimenyetso cyingenzi cyo gutandukanya ubwiza bwa methyl selulose ether.

Cyizahydroxypropyl methyl seluloseibicuruzwa bikurikirana birashobora gukemura neza ikibazo cyo gufata amazi munsi yubushyuhe bwinshi. Mu gihe cy'ubushyuhe bwinshi, cyane cyane ahantu hashyushye kandi humye no kubaka igicucu cyoroshye ku zuba, hakenewe HPMC yo mu rwego rwo hejuru kugira ngo amazi agabanuke neza; hydroxypropyl methyl selulose (HPMC), uburinganire nibyiza cyane, ni ogisijeni na ogisijeni hydroxypropyl bigabanijwe neza kumurongo wa selile, birashobora guteza imbere hydroxyl na ether ogisijeni namazi kumurongo wingenzi uhuza ubushobozi bwa hydrogène, gukora amazi yubusa, kugirango bigenzure neza ikirere gishyushye giterwa nubushuhe bwo guhumeka, Kugera kumazi menshi.

Ubwiza buhanitse bwa hydroxypropyl methyl selulose burashobora gukwirakwiza kimwe kandi neza mubisaka bya sima na pompe, hanyuma bigapakira ibice byose bikomeye, hanyuma bigakora urwego rwa firime itose, ubuhehere buri mukibanza igihe kirekire burekurwa buhoro buhoro, hamwe nuburyo budasanzwe bwa cimentitifique hydrata reaction, kugirango habeho imbaraga zububiko hamwe nimbaraga zo kwikuramo ibikoresho.

Mu bwubatsi, kugirango tugere ku ngaruka zo kubungabunga amazi, bakeneye kongeramo ubuziranengeHPMCibicuruzwa bikurikije formulaire, bitabaye ibyo, hazabaho gukama byihuse biterwa no kubura amazi adahagije, kugabanya imbaraga, guturika, ingoma zidafite akamaro no kumena ibibazo byubuziranenge, ariko kandi byongera ingorane zo kubaka abakozi. Mugihe ubushyuhe bugabanutse, ubwinshi bwamazi HPMC irashobora kugabanuka buhoro buhoro, kandi ingaruka zimwe zo gufata amazi zirashobora kugerwaho.
